firmware updater 4.0 help

Hello, I just found out about Waninkoko's new firmware updater 4.0. So I am trying to do it, my current wii system menu is 3.2 and I am at the point where I have to do the Firmware-Updater_4.0.dol part and when I do it, it says installizing network and then it says "error= ret -116". And I found out that means i'm not connected to the internet. So I went to the internet settings and they were good, I tested it, it was sucessful. So I tryed it again, it did the same thing, could someone help please?
